Embodiment Construction
[0032] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
[0033] refer to Figure 1 to Figure 5 , the present embodiment provides a waistline welding process for pull-up pants, comprising the following steps:
[0034] (1) Waistline 1 before manufacturing: a plurality of elastic bands 11 and waist non-woven fabrics 12 are transported up and down in sequence, glue is sprayed on the waistline non-woven fabric 12, the elastic bands 11 are compounded on the waistline non-woven fabric 12, and passed through the adsorption wheel The mechanism attaches the cotton block 13 to the waist non-woven fabric 12 intermittently in the longitudinal direction, the cotton block 13 is attached to one side of the longitudinal center line of the waist non-woven fabric 12, and the waist non-woven fabric 12 is folded and compounded along the center line to form a front Waist 1;
[0035] (2) Manufacturing the back waistline 2: t...

Abstract
The invention relates to a waistline welding process for pull-up pants. The pull-up pants include a front waistline, a rear waistline and an absorbing core. The cotton blocks on the front waistline and the back waistline have a buffering effect to prevent the pull-up pants from being formed on the human body. The red pull marks, the front waistline and the back waistline have a first welding part and a second welding part, the second welding part includes a plurality of point-shaped welding points, when the force is large, the welding points can be opened, which is beneficial to Control the tension of the trousers to make the trousers comfortable to wear; during the production process of the trousers, the detection and adjustment mechanism not only has a buffering effect to prevent the trousers from being elongated, but also can adjust the welding time of the welding mechanism to make the trousers The precise position of the pants during welding and cutting improves the quality of the pull-up pants. The invention relates to the field of disposable sanitary products, and solves the problem that the pull-up pants are prone to form red pull marks on the human body, and the waist circumference may be inaccurately cut and affect product quality. technical issues.
Description
technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a waistline welding process for pull-up pants. Background technique [0002] When the pull-up pants are manufactured, the welding mechanism is used for welding. When the pull-up pants are worn, the waistline is usually close to the human body. When worn for a long time, it is easy to form red pull marks on the human body, which is uncomfortable to wear, especially when the human body is squatting. The elastic band of the pull-up pants is elongated, the stretch marks are more obvious, and it is easy to cause harm to the human body. When the pull-up pants are manufactured, when the cutter mechanism cuts the pull-up pants into sheets, the cutter mechanism needs to cut the pull-up pants at the center line of the pull-up pants welding. Vibration or other factors, there may be deviations during the transportation of the trousers or stretching of the trousers during the conv...
